Abstract

For å bestemme driftsparametere for en høyfrekvent kraftforsterker (1) (for eksempel kompleks lede- og returspenning eller -effekt, kompleks belastningsimpedans, refleksjon eller standbølgespenningsforhold) på forbindelseslinjen (3) mellom utgangen fra den høyfrekvente kraftforsterkeren (1) og en kompleks belastning, spesielt en antenne (4), blir en analogt målt spenning Uu som er proporsjonal med den komplekse spenningen på forbindelseslinjen, og en analogt målt spenning Ui som er proporsjonal med den komplekse strømmen på linjen (3), bestemt ved hjelp av en Buschbeck-koblingsanordning. Disse målte spenningene blir digitalisert, og de nødvendige driftsparameterne kan så beregnes i en beregningsenhet (7) ut fra disse digitale verdiene.To determine the operating parameters of a high frequency power amplifier (1) (e.g., complex conduction or return voltage, complex load impedance, reflection or steady-state voltage ratio) on the connection line (3) between the output of the high frequency power amplifier (1) and a complex load, in particular an antenna (4), an analog measured voltage Uu proportional to the complex voltage on the connection line and an analog measured voltage Ui proportional to the complex current on the line (3) are determined by a Buschbeck coupling device. These measured voltages are digitized and the required operating parameters can then be calculated in a calculation unit (7) based on these digital values.
